Oh that's right, because of 3 or 4 fails, now EVERYTHING Microsoft spends money advertising is insta-fail. I'm sure windows 95 was probably their biggest advertising budget as far as % of market capital in their history. It was a huge success. WIndows 7, huge success. Windows XP, huge success. Office 2007, huge success. Microsoft keyboards/mice, huge success. Vista, if you had a new computer, it was amazing... if you tried installing it on a computer from the year 2000, you were doing it wrong. They just didn't understand the target market on that one.
How about the big failure that was the sony clie, or sony betamax. Come on, anything MS makes isn't insta-failure. Anything they advertise has been pretty much a success. Windows Me pretty much had no budget because windows 2000 was already out and they had realized that the NT platform was better for home computers so XP was released soon after. The Kin had a target market of teenagers, and a comparatively small advertising budget.
The best you can do is RROD? Once they realized the magnitude of the problem, they spent billions of dollars rectifying the issue. You can guarantee, that after spending $500 million on marketing, that if it costs them another $200 million to fix an unforseen problem with the Kinect, it's in their budget.
